Description:
The fluorescence of a well-characterized fulvic acid is found to be quenched by the binding of Cu(II), Mn(II) or H+. Below 40% protonation of the 5.0 mmole/g most strongly acidic carboxyl groups, the results indicate weak collisional quenching by OH−. Metal ion complexing becomes weaker with increasing amounts bound.
